One shouldn't assume ignorance on the part of creationists. That is a mistake that too many evolutionists make.   In the real world, we have people willing to say things they already know isn't true. Why should creationists be any different? After all, they are people, too. But rather than accept that fact, evolutionists argue that creationists are ignorant of a subject when, in reality, they (creationists) were simply telling lies.
